I know why my CPU didn't clear- someone snagged 5 seats. 1758 on 3/28 has five seats for one family, and they cleared at least on Wednesday. I assume that its a GS- but I guess they might have burned 5 RPUs and appear on the list also.
GSers can upgrade 5 people on CPUs? I don't mind if they used miles or even if they TOD'd on, but when 1/4 or F is going to someone- and screwing me out of my CPU, I get a little agitated. That is a crap load of seats to 'one' person.
This gets back to, if a 1K can't CPU on a MCO flight at 8am on a Saturday morning, what good is it being loyal to United?
